Signal Routing in the E-Field Plane
RF Essentials E-plane waveguide bends are precision-machined components that redirect microwave and millimeter-wave signals by curving along the wider dimension of the rectangular waveguide. This bending plane corresponds to the electric field orientation, making E-plane bends essential for signal routing in compact RF assemblies.
Available in standard 90-degree configurations across all WR sizes from WR-28 through WR-03, these bends maintain superior VSWR and minimal insertion loss. Each bend is manufactured from OFHC copper with gold plating for long-term reliability.
Key Features
E-Plane Geometry
Bend follows the wider dimension (E-field plane) of the waveguide for optimal signal routing in vertical orientations.
Low Insertion Loss
Precision-machined interior surfaces minimize signal degradation through the bend radius.
Consistent VSWR
Engineered for excellent return loss performance across the full operating bandwidth.

Frequently Asked Questions
What is an E-plane waveguide bend?+
An E-plane bend curves the waveguide along its wider dimension (the E-field plane). This redirects the signal path while maintaining the waveguide's electromagnetic mode structure. Standard configurations include 90-degree bends.
What bend angles are available?+
RF Essentials offers standard 90-degree E-plane bends. Custom bend angles and radii are available upon request for specialized system integration requirements.
How do E-plane bends differ from H-plane bends?+
E-plane bends curve along the wider dimension of the waveguide (electric field plane), while H-plane bends curve along the narrower dimension (magnetic field plane). The choice depends on the physical orientation needed in your waveguide assembly.
